Also, anyone have issues with non-brass casings? Just trying to get a jump on what ammo to buy.

When researching what to buy I had a chance to get a Witness real cheap.  After checking reviews I saw people having problems with the frame cracking under heavy load.  I've also picked up some people talking about adjusting the spring for heavy loads.  Do I have to do this or can I leave it alone and shoot different loads?  I'd like to set my red dot for personal carry ammo but haven't decided on a grain.  Thinking I'd like it to be close to range ammo. I'll look into Underwoods.  Hopefully they are available.

Hey everyone! Just ordered mine yesterday (should get it in a few days) and immediately started joining forums.  Found a small dealer who hooked me up for $699+ tax (with Hex) I bought it for carry and for bear defense (infrequent).  My question is, does the XDm hold up firing the heavy stuff? What grain should I look to stay around for bear (Flat nose hardened)? What should I get into for self defense?

Is it just that they are moving to only produce the XD-M Elite line? The elites do not appear to be discontinued.  I just ordered mine yesterday.
